JOHN B. DRAHONOVSKY, OF MILWAUKEE, VIISCONSIN, ASSIGNOR, IBY DIRECT ANDMESNE ASSIGNMENTS, 'IO AMERICAN GRINDER MANUFACTURING 00., OF MIL-WAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN.

To all whom it may concern:

Be it known that I, JOHN B. DRAHONOV- SKY, a citizen of the UnitedStates, and resident of Milwaukee, in the county of Milwaukee and Stateof lVisconsin,

have invented new and useful Improvements in Demountableliini renches,of which the following is a description, reference being bad to theaccompanying draw ings, which are a part of this specification.

This invention relates to improvements in demountable rim wrenches, moreparticular- 1y, although not solely adapted for automobile use.

It is one of the objects of the present invention to provide a wrenchhaving a plural ity of sockets of various sizes carried by the bracemember which may be adjusted for use with the brace member in a verysimple manner to fit demounta-ble rim and other nuts of various sizes.

A further object of the invention is to provide a demountable rim wrenchwhich may be adjusted to be used as an ordinary brace wrench for quicklyturning a nut, and which may be adjusted to another position whenconsiderable leverage is desired in loosening or tightening nuts on awheel rim.

A further object of the invention is to provide a demountable rim wrenchhaving means for automatically locking the socket member in adjustedposition with relation to the brace member.

A furtherobject of the invention is to provide a demountable rim wrenchwhich is of simple construction, is strong and durable and is welladapted for the purpose described.

With the above and other objects in view the invention consists of theimproved demountable rim wrench and its parts and combinations as setforth in the claims, and

all equivalents thereof.

In the accompanying drawing in which the same reference charactersindicate the same parts in all of the views:

Fig. 1 is a side view of the improved demountable rim wrench, partsbroken away and in section to show interior construction; and

DEMOUNTAIBLE-RIM WRENCH.

Application filed January 10, 1922. Serial No. 528,186.

Fig. 2 is a central sectional view of the wrench taken on line 2-2 ofFig. 1. r Referring to the drawing, the numeral 5 indicates the bracemember which comprises the cranked portion 6, the revoluble handleportion 7 and the bifurcated socket holding member 8 which is slidablymounted on the straight end portion 6' of the brace part 5. Said holdingmember 8 is formed with a tubular part 8 provided with transverseelongated slots 9 through which a pin 10 extends. Said pin also extendsthrough the straight end portion 6 of the brace part and slidablyconnects the two parts together.

A socket member 11 is positioned between the arms 12 of the bifurcatedholding memher 8 and is journaled on a bolt 13 extending transverselythrough said arms and the socket member. The socket member is in theform of a cross of tubular construction with a nut socket 14 formed oneach end and varying in size with relation to each other to fit bolts ornuts of sizes ordinarily used in connection with automobile demountablerims.

The bores 15 of the socket member 11 eX- tond centrally with relation toand open into the nut sockets 14 and are of a size to snugly receive theend portion 6 of the brace member 5 and lock the socket member in adjusted position for use as shown in the drawing.

The handle part 7 is journaled on the outer end of the brace member 5and is held in position thereon by peening the edge portion 01? thehandle into an annular groove 16 formed around the brace member.

In operation the holding member is pulled outwardly to disengage thesocket member from the brace member and the socket memher is thenadjusted to use the nut socket desired, and the holding member willautomatically slide on the brace member to lock the parts together whenpressure is'exerted on the handle in engaging the nut or bolt to beturned. If the'nut or bolt is hard to turn, it is only necessary to usethe nut socket which extends laterally and the brace may then be used asa long lever to increase the leverage.

When the nut has been sufficiently loosened.

to easily turn, the socket part may be adj usted to project from the endof the brace and the nut may then be freely turned by turn ing thecranked portion of the brace in the ordinary manner.

From the foregoing description, it will be seen that the demountable rimWrench is of simple construction, and is Well adapted for the purposedescribed.

lVhat I claim as my invention'is:

1. A demountable rim wrench, comprising a brace member, a holding membercar ried thereby, and a socket member revolubly connected to the holdingmember and adjustable to different positions for use, there being arelative movement toward each other of the brace member and the socketmember to maintain the socket member in adjusted position.

2. A demountable rim wrench, comprising a brace member, a holding memberslidably mounted on one end portion thereof, and a socket memberrevolubly connected to the holding member and adjustable to dinerentpositions for use and maintained in adjusted position by engagement withthe brace member.

3. A demountable rim wrench, comprising a brace member having a straightportion and a cranked portion, a holding member slidab-ly mounted on thestraight portion of the brace member. and a socket member revolublyconnected to the holding member and adjustable to different positionsfor use, the movement of the holding: member to Wards the brace memberlocking the socket member in adjusted position.

4;. A demountable rim wrench, comprising a brace member having astraight portion and a cranked portion, a holding member slidablymounted on the straight portion of the brace membe and having abiturcatcd end portion, and a socket member having a plurality of nutsockets, said. socket member being; medially journaled between the armsof the end portion and movable to position one of its nut sockets inregister with and to receive the end of the straight por tion of thebrace member to lock said socket member in an adjusted position of use.

5. A demountable rim wrench, comprising a brace member having a straightend portion and a cranked portion, a holding member having a tubularportion slidabl mounted on the straight end portion of the brace member,there being a pin and slot connection between the tubular portion andthe straight end portion to limit the sliding movement and preventindependent rota tion, said holding member also having a bifurcated endportion, a socket member journaled between the bifurcated portions ofthe holding. member and having a plurality of bores andnut sockets incontinuation there of, said socket member being rotatable to registerany or the bores with and to receive the straight end portion of thebrace member to lock the socket member in adjusted position and permitthe use of the nut socket in alinoment With the straight portion of thebrace member or the one at right angles thereto.

6. A demountable rim wrench, comprising a cranked brace member having astraight end portion, a holding member slidably but iwn-rotatablymounted on the straight end portion of said brace member and having abifurcated. end portion, a tubular socket member journaled between thebifurcated portions 01? the holding member and movable to position anyof its bores in register with and to receive the straight end portion orthe brace member to lock the socket member in adjusted position andpermit the use of the socket portion of the socket member in alinementwith the straight portion of the brace member or the socket portion atright angles thereto.

7. A demountable rim wrench, comprising a cranked brace member having astraight end portion, a revoluble handle mounted on the opposite end ofthe brace member, a holding; member slidably but non-rotatably mountedon the straight end portion of said brace member and having a bifurcatedend portion, a tubular socket member journaled between the bifurcatedportions of the holding member and 1novable to position any of its boresin register with and to receive the straight end portion of the bracemember to lock the socket member in adjusted position and permit the useof the socket portion of the socket member in alinement with thestraight portion of the brace member or the socket portion at rightangles thereto.

8. A Wrench oil the multiple socket type, comprising a brace, a hollowsocket holder connected to one end of the brace and located in axialalignment with the outer por tion of the brace, a socket head pivoted inthe said holder and having radially (lisposed nut sockets, and a lockingmember movable longitudinally in the hollow socket holder and into anyone of the nut sockets to hold the socket head against pivotal movement.
